To aZZ Lu/wm if may concern:

Be it known that I, JAMES W. BARNES, a. citizen of the United States, residing at Youngstown, in the county 0f Mahonin and State of Ohio, have invented a new and useful Regenerating-Furnace, of which the following is a specification.

This invention relates to regenerating furnaces. Furnaces of this type as heretofore used employ opposed gas nozzles and, op posed air passages, Vthe products of combustion, after passing through the hearth chamber, being drawn off through both the air passages and the gas nozzle. rihis has resulted in subjecting the mouth of each gas nozzle to the action of the intensely hot outflowing gases with the result that the nozzleshave soon broken down,- thus rendering the furnace unfit for further use until partly re`1 constructed.

One of the objects of the present invention is to provide a regenerating furnace having means whereby communication between each gas nozzle and the gas chamber communicating therewith is cut olf at the outflow end of the furnace so that the hot products of combustion will pass from the furnace solely through the air outlets.

A further object is to provide a novel arrangement of ports and valves by means of which the gas nozzle at the supply end of the furnace will be placed in communication with its gas chamber simultaneously with the cutting off of commi inicati on between the other gas nozzle and its gas chamber.

`With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being .understood that changes the precise embodiment of the invention herein within the scope of what is claimed, without departing from the spirit of the invention.

ln the accompanying drawings the pre ferred form of the invention has been shown.

En said drawings Figure 1 is a vertical longitudinal section through a furnace embodying the present improvements, the gas nozzles being shown in section. Fig. 2 is a section .on line A-B Fig. 1. Fig. 3 is a section online C-D Fig. 1. Fig. Il is a section on line E-F Fig. 1. Fig. 5 is a section on line G-H Fig. 1. Fig. G is a section on line disclosed, can be made I--J Fig. 2. Fig. 7 is a detail view of oneof the valves. Fig. 8 is a view showing in diagram the courses of the air, gas and products of combustion through the y furnace.

Vlheferring to the figures by characters of reference l designates the hearth chamber of the vfurnace and arranged at opposite ends of the nozzle and havingiinlet pipes 5 erf.

tending into the sides thereof as shown particularly in Fig. il.

Extending downwardly from the back portion of the bottom 'of each nozzle 2 is a gas port 6 with which communicates a gas chamber 7 the bottom of which forms a slag pocket as shown at 8. igThe chamber 7 is separated from a regenerating or checker chamber 9 by a\partition 10 having an intermediate portion 11 extending at right angles and provided with al port l2. Another partition 13 separates the chambers 7 ,rand 9 from an air chamber latin constant commuv nication with an air regenerating chamber 15. A port 16 extends through the partition 13 and is in alinement with the port. 12. A.

deflector 17 extends from partition 13 andl between chamber lll and the regenerating chamber 15. Slidably mounted between the two ports 12 and 16 is a block 18 carrying a valve 19 from one face of which extends a rod 20. This valve is so arranged that, when moved in one direction it will close the port lo and open the port 12, and, when moved in the opposite direction, it will close the port 12 and open the port 16. A gas inlet flue 21 opens into the gas regenerating chamber 9 from a gas producer, not shown, and an air inlet flue Q2 opens into the bottom portion of the regenerating chamber l5. Extending upwardly from the chamber 14: are spaced air passages 23 which open into the furnace at opposite sides of the back portion of nozzle 2, as shown at 9.4i.

It is to be understood that each end of the furnace is constructed as hereinbefore described and the rods 20 extending yfrom the the hearth chamber. Thus by directing ,iuid under pressure into one end of the cylinder 26, the portat one end Oli the turn naee vriil be clezsefl, While the corresponding 5 port at the other end of the furnace Will he cpened Whereas, when the movement of the pieton is resei'eeffl., the positions of the valves will be ieveised.

The damper mechanism for reversing the tiov ci gases Within, the furnace has :not `been illustrated but is of the form usually employed in fuinaces of this type. i/Vhen a flame .is directed into the hearth chamber from the left end et the furnace, for example7 the valves are positioned as shown in Fig. 2 so that the gas entering the regenerating chamber 9 from the flue 2l will be free to flow through port l2 and. into cham be? 7 and the-nce through the'passage t5 to the nezzle 2, While aii enteiing the chem` bei l5 at the left olf` the miiace will be free to iow' though the eliambei 1% and passages 23 to the o'fenings 24 at the sides of the nozzle 2. Thus the air and gas will 'mix at the mouth'e2 the nozzle to form e combustible mixtui'e. llhile the valve at i in position te ilovr j elle nezazle ami of e 2J-, the valve i9 t is in position. s the nozzle irnaeeis eut eut of 5 itegenerating chamtiy, there ie no pull 'e the tight epfl of the the only pif s clown.-

munication with the interior of the furnace means for simultaneously establishing coma' munication between the air and gas regenf erating chambers at the outflow end of the furnace and the interior of the furnace, closing communication between the nozzle at said end of the furnace and its gas regenerating chamber, and opening communication between the gas regenerating chamber at the inflow end f the furnace and'its nozzle.

In testimony that I claim the foregoing 15- as my own, l have hereto aixed my signature inthe presence of two witnesses.
